International Journal of vol. 25,no. 5, ABSTRACTA tunable band-notch printed monopole antenna is presented, exhibiting a wide impedance bandwidth from 1.5 to 5.5 GHz with good impedance matching (VSWR ≤ 2) and a tunable rejected frequency band from 2.38 to 3.87 GHz. The band-notching is achieved by adding an inner chorded crescent element within a driven element of a similar shape. By varying the value of the varactor which is placed between the inner and outer arcs, the desired variable rejected can be obtained. Simulated and measured results show wide impedance bandwidth with a tunable band notch, stable radiation patterns, and consistent nearly constant gain. The antenna is suitable for mobile and portable applications.

A compact substrate integrated folded waveguide (SIFW) H-plane horn antenna array with simultaneous omnidirectional and directional radiation characteristics for potential utilization to high-speed wireless communication is presented in this article. The realization of the proposed design has been accomplished by placing the apertures of nine exponentially tapered SIFW H-plane horns towards the circumference of a cylindrical substrate with an angular separation of 40 • between the horns. Every horn flaring includes a column of three slots. Centre probe feed technique has been used to excite the antenna. The radiation of the field by the horn apertures and through the slots of the horns flaring, respectively, results in an omnidirectional and a directional radiation pattern at 13.8 GHz and 18.42 GHz, with the gain of 7 dBi and 10.92 dBi. The proposed antenna has performed well and is in good agreement between simulation and measurement. The dimension of the antenna is 37.3 mm (diameter) × 1 mm (height) (1.71λ 0 × 0.046λ 0 at 13.8 GHz and 2.29λ 0 × 0.061λ 0 at 18.42 GHz). SIFW technology makes low profile antenna. The proposed design can be a promising option to be used as a low-profile antenna for high-speed wireless communication.

“…Partial ground and parasitic element also one of the technique in achieving UWB and successfully proven experimentally. According to Tseng et al, partial ground and introduction of parasitic element is helpful in providing a significant wideband impedance bandwidth . Parasitic element is the conductor material that located near to radiating elements yet it is not electrically connected with them.…”

A high performance of coaxial feed ultrawide band (UWB) array antenna with parasitic element is proposed in this article. The 4 × 1 array antenna consists of four identical copper circular patches are appropriately connected using quarter‐wavelength transformer transmission line. The array elements and its feed network are properly optimized to have a high‐gain performance over wide range bandwidth frequencies. Introduction of semicomplementary copper parasitic element with copper partial ground technique are applied in this proposed antenna to obtain optimum large bandwidth. Taconic associated with 2.2 dielectric constant and thickness of 1.6 mm is used as the antenna substrate. Less complicated fabrication methods is possible due to the feeding network placement is on the same level with the antenna patch elements. The performance of the designed antenna evaluated in term of return loss, bandwidth, radiation pattern, directivity, and gain. The proposed antenna recorded reflection coefficient less than −10 dB started from 2.5 to 12.6 GHz which fulfilling the requirement of UWB. Dimensions of 80 × 45 mm2 and maximum gain of 12.12 dB made it as small and high gain UWB antenna. The antenna exhibits a stable gain from 3.4 to 12.12 dB over the operated frequencies and has 83% of usable fractional bandwidth. The proposed antenna performance finds it very suitable to be applied in human brain microwave imaging. © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:649–653, 2015
